(Cl. Z50- 33) -14 Claims. 1,

My present invention relates ,tov high vfrequency antennae .and moreparticularly .to a television receiver antennak so constructed andarranged-to `providemaxirnum elliciency in intercepting'radiofrequencies -in the television spectrum and adapted to be-:readily setup from the collapsed [position ,to Athe fullyeerected ,position by.`simple .operations readily performable bythe 4unskilled user.

In television antennae adapted for use in connectionyvrith home typetelevision receivers, it -iscustomary toA provide :some formof vertical:supporting structureisuch as almast, ahorizontal supportingstructurewhich is usually a metallic .crosserm secured to the mast, ranintercepting dipole which may be of ,thefolded' typesupported; at oneendfof the cross farm and., insulated therefrom, Aand :a `reflectingdipole supported fat the other end of the :cross arm 4and vnot`necessarily. insulated therefrom.

lIn .thecase of: the folded.dipole,;the endsthere- Y of usuallyterminate at.;the cross arm 4where -appropriateconnectionsirnay bemadeby lead-in Ywires -to, the `television receiver.

Various attemptshave been made to form these l1-,

ydipoles :and especially the mechanical. as well fas Athe `electricalconnecting elements thereof Yin such manner that they. may vreadily zbe, assembled Without the use of complex toolson the ,cross `ofthe mast.1 .This has required, however, the utilizationof -nu'tsfand boltspassingthroughregistering open.- lings:which-mustbelined up accurately in orderto .permit assembly, tending to :make the .assembly `operation a factory.operation or lone which must be performed by a skilledxtelevisionlerectorV or serviceman.

` Where .the connection was not propel-lyv unade for insecurelytightened, as frequently occurred yinthe case of erection of thetelevision antenna by the home user, vibration ,caused by wind tended toloosen the antenna, therebycausing :tha-antenna itself` to wobble orvibratezin the vwind resulting. incinterference with; at least-videorecentierr- YThis vVibrationwhen permitted to continue-l for anyreasonable length of time tended also vto weaken and at times destroythe eifectiveoperatinsparts ofthe television antenna.

Where ,attempts havebeen made to connect =all parts of' the televisionantennadeavingthem,

lhotvever, inioldedcondition` for:y shipment and rstorage,;the frictionor other; tightening elements -used;t o, secure the ,parts `in erected;unfolded condition werev subjected c to rotary-moments of; force on arather long lever arm, especially :in the Ecase of a dipole-adapted forthe-reception-.of the low frequency band television signals,A and :theseantennae also. tended to collapse.

The object ofmy invention is :the prcmisionyof a quickly set uptelevision antenna which without the utilization of special skill or anyspecial `tools will permit a home user promptly and securely to connectthe television dipoles to the cross arm of the mast: and this connectingsetup may be made for both the main dipoles and the reflecting dipolesbythe most unskilled user within less than a minute.

Another object of my invention is to provide the dipole securingelements connectedor connectable to the cross arm of the television mastor to any other suitable supporting structure, the said connectingelements providing rigidifying elements for preventing relative movementof the dipoles with respect to the cross arm of the mast or other unitto which the dipoles are connected ;l frictionally secure positioningmeans which are not subject to any rotative moments of force and whichcan be released lonly by movement of the dipole elements in a directionwhich would not occur during the actual use of the antenna; andadditional securing means rmly locking the antenna structure andespecially the dipoles thereof in place.

Essentially, my invention contemplates the .provision of a securing orconnecting member with simplied means for mounting the same on a crossarm of the antenna mast or other appropriate antenna support.

The connecting member is channel-shaped having a longitudinal axisextending parallel to the axis of the dipole. The inner end of thedipole is shaped to fit into the longitudinal connecting member. Thevconnecting member and the dipole are so shaped that when the dipole isinserted longitudinally it is wedged in the connecting member by thislongitudinal movement, the frictional engaging surfaces extending`substantially parallel to the axis of the dipole and the frictionalWedging force being directed at a substantial angle to the axis of thedipole.

Consequently, the only way in which the dipole may be loosened from itsconnecting member ris by an outward pull parallel to the axis of thedipole. Wind vibration or other forces which may cause the dipole tovibrate have a component in a direction extending at some angle to theaxis `of the dipole and usually at right angles thereto.

Consequently, such vibrational forces would not have a loosening eect onthe dipole. In addition, the inner end of thea-dipole has a longitudinalslot preferably extending parallel to vthe axis of the dipole andengageable under the head of a bolt carried by the connectingmember, thebolt being preferably provided with a wing nut and a lock washer totighten the bolt down on the end of the dipole.

Thus, in connecting a dipole end to myvnovel connecting member, the endof the dipole need merely be slid into the end of thel connector andpushed tightly therein so that the end of the slot moves under the headof the bolt on the connector; the wing nut is then tightened.

Therefore, each dipole end requires two simple operations forconnection: (l) an inward push into the connector as far as it will go,and (2) the tightening of the wing nut. Each such operation requires buta few seconds so that an entire antenna interceptor and reflectorstructure may be assembled even by the unskilled user within less than aminute.

The mechanical connector for the dipole may be provided with anadditional opening preferably adjacent the end thereof opposite thatinto which the dipole is inserted through which a bolt may be passed forconnection to a lead-in wire; so that the only other operation requiredafter erection of the antenna is to connect the lead-in wire to thisbolt, on each side of the dipole.

My invention may take many forms, but its essential element is theprovision of means for Wedging the dipole end in position bylongitudinal movement combined with a simple operable securing means;and further combined, if desired,

With simplified means on the connecting element itself for connection toa lead-in wire.

The foregoing and many other objects of my invention will becomeapparent in the following description and drawings in which:

Figure 1 is a view in perspective showing my novel antenna structure.

Figure 2 is an exploded view in perspective showing my novel connectorstructure.

Figure 3 is a top plan View of the connector of Figures 1 and 2.

Figure 4 is a side view of the connectors of Figures 1, 2, and 3.

Figure 5 is a View in perspective showing a modified form of theconnector of Figures 1 to 4.

Referring first to Figure l, a vertical mast I carries secured theretocross arm II which preferably is a tubular metallic cross arm in orderto obtain sufcient structural strength.

The cross arm II carries clamping channel I2 having the V-shaped notchesI3, I3 which are aligned vertically to engage the mast I0. A U- shapedbolt I4 is arranged to surround the mast I0, the legs of the U-shapedbolt I4 passing through openings I in the cross arm II and throughsimilarly aligned openings in the chan- U-shaped bolt I4 toward the baseof the channel I2 making a clear space between V-shaped notches I3 andthe bend of the U I4 smaller until the mast IIJ is tightly clamped.

This particular securing or integrating member for connecting the crossarm II to the mast I0 forms no part of my present invention but isdescribed and shown herein only for the sake of completeness. Anysuitable means may be used to obtain this interconnection between thecross arm II and the mast I0.

The ends of the cross arm II are collapsed at 20, 2| to provide a flatsurface on which the interceptor dipole and the reflector dipole may bemounted.

In Figure 1 there is shown a folded dipole for interception of the highfrequency waves. The folded dipole comprises the pair of metallic tubes26, 21 bent into a U-shape and collapsed, respectively, at their ends28, 29 and 30, 3|.

The ends 28 and 29 of the U-shaped section 26 and the ends 3U, 3| of theU-shaped section 21 are collapsed in such manner as to produce arelatively flat center 35 and longitudinally extending lateral'ribs 36,31. (See also Figures 2 and 4.)

The tube end 28 illustrated in Figures 2 and 4 and the other tube endsas well are also so collapsed as to produce the chamfered connection 40at each side between the body of the tube and the lateral longitudinallyextending ribs 36, 31.

The end of the tube at the flat section 35 ls provided in each case withthe longitudinally extending slot 42 communicating with the end of thetube and open thereat. Each of the connecting elements 45 is providedwith a pair of parallel side walls 46, 41 extending substantiallyparallel to the axis of the connector and substantially parallel to theaxis of the tube to be inserted therein.

However, the walls 46 and 41 taper toward each other so that the spacebetween them at end 48 of the connector is narrower than the spacebetween them at end 55 of the connector. The ribs 36, 31 at the end 28of the tube are spaced apart so that their outer transverse dimension isless than the distance between the parallel Walls 46, 41 of theconnector 45 at end 50 but is greater than the distance between thewalls 46, 41 at end 48.

As a matter of fact, the walls 46, 41 taper together quite close to theend 50 to a degree where they will tightly engage the ribs 36, 31.

The ribs 36, 31 of the tube end 28 in essence form an I beam with thetube section 35 and are substantially incompressible.

The walls 46, 41 of the connector 45 are of relatively strong metal; butare sufficiently resilient so that they may be resiliently spread by theinsertion of the tube end 28 therebetween with sufficient force andowing to their resilience will frictionally engage tightly against thesides of ribs 36 and 31.

In addition, the connector 45 is provided with the bent-up Wall 52adjacent the end 5D, the said Wall 52 having the horizontal slot 53 topermit passage thereinto of the flat section 35 of end 28 of tube 26,the tube 26 being taken by way of example and being representative ofthe other tubes.

Communicating with the flat horizontal slot 53 are the vertical slots54, 54 in the bent-up wall 52. These vertical slots 54 are dimensionedso that they will readily receive the ribs 36 and 31 and permit theentire unit thereby to be inserted into the connector 45.

They are, however, so dimensioned that the chamfered portions 40 of theribs 36 and 31 which connect them with the tube 26 can slide in onlypart way before engaging in tight frictional engagement with thematerial defining the vertical slots 54, 54.

The force necessary to push the tube end home in the connector willresult in a slight deformation of the portion of the wall 52 definingthe slots 54 as they are forced up onto the chamfered portions 40 of thetube 26. This deformation is also a resilient one creating a linefrictional engagement at substantial pressure which serves to anchor thetube in place.

As the tube end 28 is pushed home, the slot 42 moves under the head ofbolt 60 which passes through opening 6I. Bolt 60 may be tightened inplace by the wing nut 62. and an appropriate vby the bolt66 and the nut61. through opening 6| of the connector and aligned "gagsevgsvvldckwasher'may be used. This serves mechani- `'callytoanchor the tubeen'd in'place.

By this means, therefore, any lateral vibrat.

ing force transverse to the axis. of tube 26 will have no component offorce tending to loosen vibrating force to which the tube may reasonablybe subjectedwill 'have a component in that direction. In vadditionthebolt 60 rand wing nut 62.provide. a secure mechanical arrangement.

Thus, Ain order to anchor the tube 26 in the connector, it is necessaryonly to insert the flat- -tened end thereof through the composite slot54,

Since the connector is metallic, it may be made-of suitably conductivematerial and provide'an appropriate means of securement for a `lead-inwire. This means of securement for the lead-in wire is providedvat end48 of the connector by the opening 65, the bolt 66 passing through theopening and the nut 61 which provide a means for securing the terminallug of the lead-in wire or the lead-in wire itself to the end 48 of theconnector 45.

` While Figures 1 vto 4 show the preferred form -of my novel connector,it will be obvious that it may'assume many other shapes within theprinciples of my invention.

Thus, in Figure 5 I have shown a modiedform of connector |45 having theopening |6| to receive a bolt and wing nut assembly similar to -the boltand Wingnut assembly 62 of Figure 2.

Instead of the parallel walls 46, 41 and the end Wall 52 of theconnector of Figure 2, I provide curled-over channel members l 46, |41in the These will receive the ribs36, 31 of the end 28 of tube 26, thechamfered por- Vtion of the tube pressing into the edges 200, 200

ofthe connector |45 When'the'tube is pushed home.

Here again the channels |46 and 141 may be tapered'toward each other toprovide a tight 'frictional resilient engagement'of the ribs 36 V and 31in connection with the frictional engagement of the ends 200 of channels|46 and |41 on the chamfered surfaces 49 of the tube.

'The other operations, aswell as the advantages of the unit of Figure 5,are substantially the same as those previously described in connectionwith the unit of Figures=l to 4.

In iFigures l and 2I have shown apreferred "manner in which theconnector maybe embodied commercially for use in connection with theantenna structure.

An insulating plate or bracket 90 is providedV with longitudinallyaligned openings 9|, 92, 91a, 92a. A connector 45 is secured to the pairof openings 9|92, and another connector 45 reversed 180 is secured tothe aligned openings Bolt 66 passes through opening 92 of the insulatingbracket 90 and opening 65 of the connector 45, the connector being,therefore, held in place Bolt 60 passes opening 9| ofthe; insulating.bracket-90 where 'it is held in placeby the Wingnut 62.

Wing nut 62 need not be .removed from the bolt 60 in ordertoprovide forsecurementof the antenna thereto .as `previously described since theslot 42 simply 4slides under .thehead of `bolt Bolt 66 need. notberemoved completelybut need merely be loosened in order toV provide, .forthe insertion under the head thereof of anantenna 1ead-in connector clipor of a turn or two of the. lead-in wire itself.

Where the connector clip is a full annular'tclip, then, of course, thebolt 66 must be temporarily removed to slide the clip over the same. The

connection of the lead-in wire may, if desired,

be made at the factory for standard lengths since the lead-in wire mayreadily be coiled up and `.will not interfere with the arrangementlofthe antenna structure in a small package for shipment. v

The antenna parts, however, are. disconnected during shipment andare-inserted in position-b the simple method vpreviously described.

The insulating plate or bracket is also provided with Va pair ofAtransversely aligned openings 95, 96 for securement to the collapsedend'20 of cross arm that is, a pair of bolts 91,98 are passed throughopenings 96, and appropriately spaced openings in the collapsed end 20of cross arm l and are held in place by nuts.

Thus, where a straight dipole is used, the only operation required inassembly is to pass'the bolts 91,98 through op'enings'96, 95 .and then.through the aligned openings in the collapsed end-20 of cross arm andzsecure them'in place by nuts. The two dipoles are .then forced into theopposite connectors 45 and secured `in position as previously described.

This is also true in the case of a folded dipole,

lthe ends of the dipole being sufficiently 'flexible and the relativeamount of movement being such as to permit this kind of connection to bemade.

Where, however, the 'folded dipole is-too rigid to permit this to bedone or where the Vfolded dipole is a large one for use'primarily onrelatively low frequencies, then the folded dipole is shipped in twoparts 26, 21 each bent in U-shapedform as shown in Figure 1.

In this case, a U-shape'd bracket |00 is secured to the top of theinsulating bracket 60 (on'the side opposite the securement of bracket 92on the cross arm Il so that bracket |00 will be insulated therefrom) bythe bolts 91, 98.

A connecting plate |90 of metal is secured by bolts |9|, |92 and nuts|93, |94 to the upper leg of the bracket |00. The connecting'plate |90carries the upper pair of connectors 45 identical with the rconnectors45 carried by the lower bracket 90.

The two ends 28, 29 of theU-shaped tube 26 are pushed in simultaneouslyin the upper and lower` brackets onthe right side rof Figure land thetwo ends` 30 Aand 3| of the' U-shaped tube'21 are'pushed insimultaneously in the upper and lower connectors 45, 45 on the left sideof Figure 1. The metallic strip |90 serves, to completethe folded dipoleat its upper leg.

The base of the bracket |00 is, of course, spaced from the inner ends ofthe lower connectors:l 45, 45'so that the dipole is not short circuited.

The reflecting antenna 225 comprises a pair of tubes 226, 221 shaped attheirv inner ends 23|, 229 to correspond exactly with the shape shownfor the tube 26 of Figure 2. The connectors 45 are mounted on a rearmetallic plate 299 secured to the. collapsed rear end 2| of. the crossarm. Il

by the bolts 25|, 292 passing through appropriate openings in thecollapsed end 2| of the cross arm and being held in place by appropriatenuts.

An insulating bracket similar to the bracket 90 may be used, wheredesired, but for utilization as a reilecting antenna it is preferredthat the reector 225 be a single cross bar electrically in engagementwith the cross arm and the lmast I0.

the antenna will be the home user himself, then preferably the cross armhas secured thereto the insulating bracket 90, the bracket |00, and theAbracket |90 at the front end and at the opposite end the bracket 290together with the six connectors normally carried thereby.

Since the bracket 90 need be no more than of the order of six incheslong, the maximum Width of the package in one plane need be no more thansix inches and the other elements of the antenna, of course, may beappropriately nested in the package.

Where the package is to be flattened to say a maximum width of one inch,then, of course, brackets 90, |90, and 290 mut be disconnected from thecross arm.

When, however, the home user receives the cross arm with the bracketsthereon, the only operation he must perform is to push the ends of thedipoles into the connectors and tighten the wing nuts.

If the lead-in Wire has not already been connected to bolts 66, then, ofcourse, they should be connected to these bolts or they may even beconnected under the wing nuts to bolts 5G where required.

Thus, to connect the dipoles to the cross arm the only operation thatneed be performed is the single longitudinal movement of each dipoleinto its connector and the tightening of the wing nut.

This is the essence of my invention.

In addition, the simplified means provided for connecting the lead-inwire makes such a connection obvious and easily performed.

The connectors may be delivered mounted on their appropriate brackets sothat where the brackets must be disconnected from the cross arm tofacilitate shipment it is only necessary to pass a pail` of boltsthrough aligned openings of the bracket and the cross arm to connect thebracket to the cross arm.

By this means, therefore, an antenna structure is provided which may bereadily and quickly erected and locked in position which is mechanicallystrong enough to survive weathering and wind forces and which will notbe disrupted by vibrational forces.

In the foregoing I have described my invention solely in connection withspecific illustrative embodiments thereof. Since many variations andmodifications of my invention will now be obvious to those skilled inthe art, I prefer to be bound not by the specific disclosures hereincontained but only by the appended claims.
